IBAN.im

Shorten, create and share memorable links for IBANS

BIG REFACTORING STARTED

Purpose

Shorten IBAN numbers with url such as :

• iban.im/user/alias
• iban.im/fakturk/garanti

Stacks

Backend

• Go
• GraphQL : graphql-go
• ORM : gorm

Frontend

• Vue 3
• Vite
• Tailwind CSS v4
• Vue Router
• Vuex

The frontend is built and embedded into the Go binary as static files, creating a single deployable artifact.

Features

• New users should Sign Up & Sign In
• Change a Password of user
• Change a Profile of user
• Delete a Profile of user
• Get Profile of user
• New IBAN add for user
• Update IBAN for user
• Delete IBAN for user
• Get IBAN's of user
• When adding new IBAN check if is it exist with same name (we can add with different names)
• A user should add iban to only itself

How to Run

Docker Development (Recommended for Local Development)

The easiest way to get started with development is using Docker with hot reloading:

# With PostgreSQL (recommended)
docker compose -f docker-compose.dev.yml up

# With SQLite (lightweight)
docker compose -f docker-compose.dev.sqlite.yml up

See DOCKER_DEV.md for complete Docker development documentation.

Manual Setup

Initialize DB

1. Create a database

postgres=# CREATE DATABASE ibanim;

2. Create a user as owner of database

postgres=# CREATE USER ibanim WITH ENCRYPTED PASSWORD 'ibanim';

postgres=# ALTER DATABASE ibanim OWNER TO ibanim;

3. Grant all privileges to user for the database

postgres=# GRANT ALL PRIVILEGES ON DATABASE ibanim TO ibanim;

4. Configure the db in db.go

// ConnectDB : connecting DB
func ConnectDB() (*DB, error) {
	db, err := gorm.Open("postgres", "host=localhost port=5432 user=ibanim dbname=ibanim password=ibanim sslmode=disable")

	if err != nil {
		panic(err)
	}

	return &DB{db}, nil
}

or with Docker

host address should be edited to host.docker.internal to connect a host interface.

// ConnectDB : connecting DB
func ConnectDB() (*DB, error) {
	db, err := gorm.Open("postgres", "host=host.docker.internal port=5432 user=ibanim dbname=ibanim password=ibanim sslmode=disable")

	if err != nil {
		panic(err)
	}

	return &DB{db}, nil
}

Initial Migration

$ go run ./migrations/init.go

or with Docker

$ docker build -t ibanim .
$ docker run --rm ibanim migrate

This will generate the users table in the database as per the User Model declared in ./model/user.go

Build and Run the server

The frontend is embedded into the Go binary. You must build the frontend first, then build the Go application.

Option 1: Using Makefile (Recommended)

$ make build
$ ./iban.im

This will automatically build the frontend and copy it to static/dist/ before building the Go binary.

Option 2: Manual Build

# Build frontend
$ cd web
$ npm install
$ npm run build
$ cd ..

# Copy frontend to static package
$ cp -r web/dist static/

# Build Go binary
$ go build
$ ./iban.im

The server will serve both the API (GraphQL) and the frontend (Vue.js SPA).

or with Docker

$ docker run --rm -d -p 8080:8080 ibanim

Frontend Development

The frontend is a Vue 3 single-page application (SPA) with Tailwind CSS. For detailed information about building and embedding the frontend, see FRONTEND_BUILD.md.

Development Mode

For frontend development with hot-reload:

cd web
npm install
npm run dev

The development server runs on http://localhost:4881 and proxies API requests to http://localhost:4880.

Building the Frontend

cd web
npm run build
cp -r dist ../static/

Then rebuild the Go binary to include the updated frontend:

go build

GraphQL Playground

Connect to http://localhost:8080

Authentication : JWT

You need to set the Http request headers Authorization: {JWT_token}

Configuration

You can configure the app via environment variables and/or YAML files. Load order and precedence:

1. Built-in defaults
2. YAML files (if present): config/database.yml, config/smtp.yml, config/application.yml
3. Environment variables (highest precedence)

Supported environment variables:

• PORT
• ENV
• DEBUG
• TIMEOUT
• MAX_REFRESH
• AUTH_KEY
• REALM
• DB_ADAPTER
• DB_HOST
• DB_PORT
• DB_NAME
• DB_USER
• DB_PASSWORD

Example .env file (copy to .env and adjust as needed):

# Application
PORT=7000
ENV=localhost
DEBUG=false
TIMEOUT=60
MAX_REFRESH=60
AUTH_KEY=12345678
REALM=ibanim zone

# Database
DB_ADAPTER=postgres
DB_HOST=localhost
DB_PORT=5432
DB_NAME=ibanim
DB_USER=ibanim
DB_PASSWORD=ibanim
